Snail Mail Still Winning The Bandwidth War 259

LR_none writes "Today's New York Times has this short piece suggesting snail mail is the leading broadband technology, at least for video movies on demand. The article states that the 8 to 9 gigs of data on a DVD would take two weeks to download at 56kb, making Netflix' three-day distribution by mail seem speedy. (Since they can send three or more movies at once, Netflix compares favorably with DSL download speeds, too.) The author estimates Netflix alone distributes 1,500 terabytes a day, which is impressive considering the Internet carries 2,000TB a day (by estimates cited in the article). The 'immediate gratification' aspect of Internet consumerism has given a huge boost to companies like FedEx and UPS, but it's surprising to think of the post office as being the leading infrastructure provider for digital entertainment, in terms of market share and efficiency, for the forseeable future. (Disclaimer: I don't work for Netflix or the post office.)"

    The MPAA claims that the internet has creates significant consequences and risks -- citing to supposedly a kazillion feature films being pirated daily. This simple piece of arithmetic is a useful hunk of rebuttal.
    • by Anonymous Coward
      A rebuttal of what, exactly?

      Is there some connection between the number of pirated movies available on the Internet and the number of non-pirated movies rented out by Netflix that's never been brought to light or something?
      • It rebuts (sp?) the claim that the internet poses unique and dangerous threat.

        With 7.4 million DVD rentals per day in the US http://www.showbizdata.com/contacts/ and assuming 7GB per DVD average and ignoring the "features disks", the effective bandwidth of the DVD rental system is 52,800TB/day.

        This implies that if the daily bandwidth of the internet were entirely DVD movies, this would constitute 3.8% of the total DVD rental market. (ignoring the DVD sales market for the moment) 3.8% is not "commercially significant" and doesn't affect the "fair market value of the work". It sounds (if memory serves) less the than the cost of shoplifting or credit card fraud.

        According to Jack Valenti there will soon be 1M movie downloads per day worldwide http://www.mpaa.org/jack/2001/2001_04_03a.htm . This would constitute (if true) 15% of the *US* rental market (which is apples to oranges worldwide vs. US -- so derate by the ratio of the worldwide market to the US market). It would also imply that (even assuming 700MB Divx of VHS quality) that 35% of the total internet traffic (700TB/day) is movie downloads.

        If anyone believes that I've got some swamp land and a bridge for sale.
      • internet is somehow a faucet of distribution with which material and physical distribution cannot meaningfully compete. It is arguably faster and more efficient to distribute DVD's using the mails -- thousands of terabytes per day can be distributed far more efficiently (and cost effectively) in this manner than upon the internet.

        The threat to distribution is not that it exists at all (you can find pirated DVD's on most any city street), but whether it is significant compared to the principal modes of distribution available to legitimate parties.

      So Fed-Ex is shipping in less than 10 seconds these days? A 1 Gbit link is just a matter of some money. Any big ISP should be able to sell you that and actually deliver as long as both endpoints are on the same, bigish, ISP.

      If we were talking a factor 1000 more than 1GB, the Fed-Ex solution might have some validity. But then you have to take into account high-bandwidth tape drives in parallell and so on. My guess that you would be very hardpressed to find a solution that is faster than the internet for getting data from one file system in one city to another file system in another city. /Mattias Wadenstein

      You can't stream the mail.

      Streaming snail mail doesn't work for DVDs, but you can get it to work for VHS.

      The trick is to pull one end of the tape out of the cartridge, then glue it to a post card. Drop the postcard in the mail and leave the rest of the tape next to the mailbox.

      Now, as the head end of the tape makes its way through the postal system, it automatically despools the rest of the tape which streams along behind it.

      As soon as the head end of the tape arrives, the customer inserts it into in an empty cartridge and starts to play it . As the VCR plays, it sucks the remainder of the tape out of the postal system at the appropriate speed.

    • You can't stream the mail

      Yes you can. Think about it.

    • Arent periodicals/magazines "streaming" information to you? A chunk of bytes arrives today .. the next chunk a week later ... high latency, but still streaming. :)
    • You can only stream if you can cache enough of the content first before starting the movie. DVD's have a huge throughput that your average 512kbs connection would not handle. Just try and download a linux iso and repeat 10 times. Thats how long its gonna take to get your movie down.

      Oh and if you live in Australia then they are gonna charge you for going over your bandwidth limit. So you have 3 choices. Netflix and 3 day lag, Download and possible data charges, or forsake quality and and download divx versions of the movies. /b

    if you live on the East Coast, forget about it. Mail takes 5 business days, coming and going, making Netflix not all that cheap. If you get the basic service (3 movies at a time), if you watch the movies THE DAY you get them and send them back immediately, you still can't realistically get more than say, 6 movies a month. If Netflix opened a warehouse on the East Coast, shit, I'd get the best damn service they've got. If not for that huge mail lag for us on the East Coast, their service is fucking fantastic.

      Netflix and I handle all of the "pinging" (i.e., the administrative tasks such as creating an account, placing an order, and tracking progress) via the web & email--almost instantaneously.

      Then we handle the high-volume data transfers via USPS, which works out pretty nicely. Sure, there's about 5 days of latency (from the time I return a DVD to the time the next one arrives), but the way it works out I generally have one or more new movies waiting for me whenever my schedule allows me the time to watch one.


    • Cost is also an issue, next-day mail is REALLY expensive... shooting bits across the net is really cheap, and in comparison almost free.


      Where do you live? Next day mail costs me £0.26 (~$0.35). On the other hand, if I had a dialup modem I'd be paying double that per hour to "shoot bits across the net". Luckily I have DSL, but that's not cheap either.

  • "Broadcast quality" video requires about 5Mb. A cable system that carries 70 channels should therefore have at least 300Mb/s raw bandwidth. That's enough to download a 9GB movie in four minutes. One third of that would be enough to download the top 120 movies once a day. 1/36 of that would be enough to download 8 hours of network programming for each of five networks, for on-demand viewing, still leaving more than half the total bandwidth unused.There's lots of bandwidth out there, but people are too busy worrying about intellectual property rights to take advantage of it. Until we have an approach that separates compensation to artists and producers from distribution, our distribution system will remain wildly irrational.
    • You're doing the math wrong. Assuming broadcast quality video needs 5MB, a 70 channel cable system needs....5MB. A 400-channel cable system needs 5MB. Ever notice how you're never watching more than one channel at once? Maybe a little more to download guide data. But your cable line isn't 300MB.

    I joined Netflix [netflix.com], one of the first of the DVD rental mailer companies, a long time ago and like it a lot. I was interested, then, to read a rough calculation [nytimes.com]that, in terms of 190,000 MPEG-2 format DVDs, Netflix's daily bandwidth totals 1.5 TB. This is a sizable fraction of the current total estimated Internet daily bandwidth: somewhere between 2-4 TB. Of course, Peter Wayner's [wayner.org] calculations do not allow for the online delivery of movies in more compression-efficient formats, such as the MPEG-4-derived DIVX, where a typical 4-7 GB DVD can be reduced to around 700 MB with minimal quality loss.

    I guess the CD manufacturers also thought they were safe, when a typical CD occupied 700MB of data in an era of mainly dialup connections. Then along came MP3 with its one-tenth compression ratio and so much for that idea. Netflix's current success is a temporary artifact of our restricted bandwidth and lack of suitable MPEG-4 hardware players.

    And I found out from some surfing that some Netflix competitors, such as CafeDVD [cafedvd.com], QwikFlicks [qwikfliks.com], and DVD Avenue [dvdavenue.com], are cheaper and offer porn, something Netflix avoids.
